associated phenomena; and a thorough study of any of its facts is certain to yield important scientific results. The phenomena of advance and recession of the glacier termini, the former extent of the glaciers and their deposits, and the stupendous work which they have accomplished in sculpturing the wonderful series of fiords are among the phenomena demanding attention. The features exhibited have far more than local importance and application, for the fact that we have here large glaciers descending to sea level in a comparatively-warm, humid, north temperate climate gives rise to phenomena resembling those of the wasting margin of the great continental ice sheets of North America and Europe, and, therefore, throw light upon and furnish aid in interpreting these phenomena.
